Hey there, came across the Godot Engine, those guys made a alternative Collada Exporter,
at first glance it seems much better compared to the one that comes stock with Blender itself.
The tests in T3D i did so far, all worked without issues,
one of the best pros seems to be that when you ReImport your Collada(.DAE) Model back into Blender,
you get your Mesh the Way you exported it (you get Quads and no Tris, makin the ReImported Mesh editable
again, therefore no quality loss when it comes to geometry)
You can grab the Blender addon here:
or Direct Download Link:
How To Install it?!:
1. Open User Preferences (Ctrl+Alt+U) and under Add-ons, click Install from File. Then navigate to the file you downloaded and select it.
2. It should now appear in the window and you can tick the checkbox in the upper right to enable it.
3. If you would like to have the add-on enabled every time you start Blender, click Save User Settings at the bottom.
Would like to hear your experiences with this Alternative Addon for Blender.
HF and happy Blending
